A/C Repair Service for Your Mercedes-Benz GL550

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Your steering wheel feels like lava. Sweat soaks the driver's seat. You wipe your brow and wonder, "Who can fix the A/C in my Mercedes-Benz GL550?" Firestone Complete Auto Care — that’s who! We’ve got experience with Mercedes-Benz vehicles, and our qualified technicians can diagnose and service the A/C system in your 2009 Mercedes-Benz. Come to your local Firestone Complete Auto Care in your Mercedes-Benz GL550

During an A/C performance check, we'll determine the condition of your 2009 Mercedes-Benz GL550 A/C system to see if repair work is required. This check includes a visual inspection, performance test, and pressure and leak test. If any signs point to a possible leak, we’ll send a special U/V dye through the system, or use something called a “sniffer.” What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your Mercedes-Benz GL550 A/C system to detect refrigerant fumes escaping from the system. If your system has a leak, we can get it fixed.

GL550 A/C Recharge

When we perform an A/C repair on your 2009 Mercedes-Benz GL550, we’ll also do an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Then, they’ll perform an evacuation (also known as a discharge) on the entire system per Mercedes-Benz guidelines. The A/C system is recharged with new refrigerant and after one final test to be sure the system is cooling properly, you’re good to go. Our technicians are trained to efficiently perform 2009 Mercedes-Benz GL550 A/C recharges.

Troubleshooting Mercedes-Benz GL550 A/C Problems

Warm air isn't the only Mercedes-Benz GL550 A/C problem you may encounter. Another common A/C problem is weak airflow, which could mean you have a compromised seal, mildew or mold buildup, a loose or damaged hose, or a ventilation fan that needs to be replaced. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this may suggest a leak, a blown fuse, or a damaged compressor clutch. Are you breathing in some “interesting” new odors in your 2009 Mercedes-Benz GL550? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Our trained technicians will do what they can to solve your A/C problems. We’re here to help you get back on the road in your GL550 — without all the sweat puddles!

Frequently Asked Questions for 2009 Mercedes-Benz GL550 A/C Systems

  • How can I make my GL550 air conditioner colder? Park in the shade whenever you can, and use a reflective sunshade in the windshield when you’re parked. If you’re the only one in the car, close all the vents except the ones that point toward you. Give the system the final boost it needs with an A/C performance check and recharge from Firestone Complete Auto Care.
  • Why do I get hot air from my GL550 A/C? Maybe your A/C starts cool but then gets warm. Or maybe it never gets cold in the first place. Either way, your A/C troubles could be traced back to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak.
  • What causes A/C system leaks? A/C system leaks are often due to a combination of age and moisture. Rubber seals and gaskets naturally degrade over time, allowing refrigerant to exit and moisture to enter your GL550's A/C system.
  •  Does running the A/C in my GL550 use gasoline?  The air conditioning system in your GL550 does not use gasoline directly as a fuel source, but it does require some power from the engine, which indirectly affects your car's fuel consumption.
  • What does it mean if the A/C in my GL550 smells like vinegar? If a vinegar-like odor comes from your A/C, bacteria growth could be the culprit. Moisture accumulation in the air conditioning system of your GL550 creates a breeding environment for microorganisms.
  • Why does my vehicle have to be moving for my GL550’s A/C to work? Damaged or worn components in your GL550’s electrical or air conditioning system can cause the A/C to only work when the car is moving. You may be dealing with low coolant or a faulty cooling fan.
